Pac ko Morales in Morales vs Pac 2 but there was a rematch.
Pac tko Barrera in Barrera vs Pac 1 but there was a rematch.

The list could go on for the same reason. It is all about the money. Pac has 2 wins against Marquez not to mention it should be 3 because of the admitted judge scoring error vs Marquez 1 win against Pac. So it was 3 > 1 in favor of Pac.

If Pac beat Marquez again in a close fight or better ko him for good. There should be no rematches. These two fighters are are evenly matched but Marquez legacy is only based on his 1 win vs Pac 3 wins.

You think Marquez won all those first 3 fights but that was just your opinion. In reality those were all close fights and far from a robbery like you are trying to say. If you want to learn about boxing robbery then watch Pac vs Bradley fight and Pac didn't even cry for it everyday and like a man just accepted it as it is.
